Poorly designed excitation signals could lead to inaccurate or, even worse, highly correlated parameter estimates in a data-driven model, so it is critical to have an informative training data set in order to obtain an accurate model in a cost effective manner. This paper investigates a sequential optimal design of experiments (DOE) approach to generate an optimal training data set for varying zone...
Buildings served by multiple rooftop units (RTUs) are widely prevalent in retail and food industries. Till date, most of such buildings utilize plain feedback or heuristic strategies to determine the RTU operations. We present a switched dynamic programming based approach for scheduling rooftop unit operations in an optimal manner. Using a mid-size restaurant served by multiple RTUs as an example,...
The ubiquity of on-demand cloud computing resources enables scientific researchers to dynamically provision and consume compute and storage resources in response to science needs. Whereas traditional HPC compute resources are often centrally managed with a priori CPU-time allocations and use policies. A long term goal of our work is to assess the efficacy of preserving the user environment (compilers,...
Although shared memory programming models show good programmability compared to message passing programming models, their implementation by page-based software distributed shared memory systems usually suffers from high memory consistency costs. The major part of these costs is inter-node data transfer for keeping virtual shared memory consistent. A good prefetch strategy can reduce this cost. We...
In this paper, we proposed a novel simulation scheme, called data-dependency-aware synchronization and scheduling, for SoC virtual platform simulation. In contrast to the conventional clock-or transaction-based synchronization, our simulation scheme can work with the clock decoupling and direct-data-access techniques to implement the trace-driven virtual synchronization methodology. In addition, we...
Network Simulation is a new network design and optimization technology, it can provide a reliable quantitative basis for networkpsilas planning and design, and it also can verify the actual project or compare a number of different designs. In this paper, we introduce OPNET network simulation softwarepsilas main features, modeling mechanism and simulation steps. Given an example for a home network,...
This paper presents a novel simulation technique for SoC virtual platforms at transaction level to achieve million-instructions-per-second (MIPS) level of simulation speed, while retaining accurate and detailed cycle information for system explorations. We first apply virtual synchronization concept to our simulation algorithm and then apply a novel data-dependency aware concept to determine precise...
